Overhead storage bin latch system

ABSTRACT

A latch system that includes a paddle button assembly having a button that is movable between home and actuation positions, a latch assembly that includes a striker assembly with a striker and a hook assembly, and a cable that extends between the paddle button and latch assemblies. The hook assembly includes a hook, a pivotal trigger arm, and a manual override switch that is movable between first and second positions when the trigger arm is moved from an engaged position to a disengaged position. Movement of the button from the home position to the actuation position pushes or pulls the cable, thereby pivoting the trigger arm from the engaged to the disengaged position and disengaging the hook from the striker. Pivotal movement of the trigger arm from the engaged to the disengaged position results in linear movement of the manual override switch from the first to the second position.

FIELD OF THE INVENTION

The present invention relates generally to a latch system, and more particularly to a latch system for an aircraft overhead storage bin.

BACKGROUND OF THE INVENTION

Overhead storage bins in aircraft typically include latching systems to secure the pivotal bucket to the upper housing. However, many latch systems have proven unreliable. Accordingly, a need exists for an improved latch system. U.S. Patent Publication Nos. 2014/0197721 and 2015/0307192 are incorporated by reference herein in their entireties.

SUMMARY OF THE PREFERRED EMBODIMENTS

In accordance with a first aspect of the present invention there is provided an aircraft storage bin that includes an upper housing that includes first and second side panels, a bucket that cooperates with the upper housing to define a bin interior, and a latch system. The bucket is movable with respect to the upper housing between an open position and a closed position and includes a bottom and first and second side walls. The latch system includes a paddle button assembly having a button that is movable between a home position and an actuation position, a first latch assembly that includes a first hook assembly and a first striker assembly, and a first cable that extends between the paddle button assembly and the first latch assembly. The paddle button assembly is associated with one of the bucket and the upper housing. The first hook assembly is associated with one of the bucket and the upper housing and the first striker assembly is associated with the other of the bucket and the upper housing. Movement of the button from the home position to the actuation position moves the first cable, thereby disengaging the first hook assembly and the first striker assembly, thereby causing the bucket to move from the closed position to the open position. In a preferred embodiment, the first hook assembly includes a first hook and the first striker assembly includes a first striker. Movement of the first cable moves one of the first hook and the first striker to disengage the first hook assembly and the first striker assembly. Preferably, the button is pivotal between the home position and the actuation position and the pivotal movement of the button pushes or pulls the first cable, thereby pivoting a first trigger arm from an engaged position to a disengaged position and disengaging the first hook from the first striker.

In a preferred embodiment, the first hook assembly includes a first rotary member that includes the first hook. The first rotary member is movable between a first position where the first hook is engaged with the first striker and a second position where the first hook is not engaged with the first striker. Preferably, the first rotary member is biased toward the second position. In a preferred embodiment, the first rotary member includes a first catch member that engages a first ledge on the first trigger arm in the first position and a first stop member in the second position. The first rotary member is preferably enclosed in a housing and includes a first closeout member. The housing includes a striker opening defined in a top wall thereof and the first closeout member is positioned to block the striker opening when the rotary catch is in the second position.

In a preferred embodiment, the hook assembly includes an indicator that is movable from a first position to a second position when the trigger arm is moved from the engaged position to the disengaged position. Preferably, the indicator is enclosed in a housing and extends outwardly from the housing when in the second position. In a preferred embodiment, the button is pivotal between the home position and the actuation position, and pivoting of the button pivots a cam member that pushes or pulls the cable, thereby disengaging the hook from the striker. Preferably, the cam member includes a cam post extending outwardly therefrom that engages a cam surface on the button, and the cam post moves along the cam surface when the button pivots from the home position to the actuation position.

In accordance with another aspect of the present invention there is provided a method of closing a storage bin that includes the steps of moving a bucket from an open position to a closed position and toward an upper housing. One of the bucket and the upper housing includes a hook assembly and the other of the bucket and the striker includes a striker assembly. The hook assembly includes a rotary member that includes a hook and a closeout member, and the striker assembly includes a striker. The rotary member is movable between a first position where the hook is engaged with the striker and a second position where the hook is not engaged with the striker. The step of moving the bucket from the open position to the closed position causes the striker to contact the closeout member, thereby rotating the hook from the second position to the first position.

In a preferred embodiment, the first paddle button assembly includes a first indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position. Preferably, the first paddle button assembly includes a first indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position and the first hook maintains the first trigger arm in the disengaged position when the first rotary member is in the second position, thereby maintaining the indicator in the second position.

In accordance with another embodiment of the present invention there is provided a latch system that includes a paddle button assembly having a button that is movable between a home position and an actuation position, a first latch assembly that includes a first striker assembly and a first hook assembly, and a first cable that extends between the paddle button assembly and the first latch assembly. Movement of the button from the home position to the actuation position moves the first cable, thereby disengaging the first hook assembly and the first striker assembly. Preferably, the button is pivotal between the home position and the actuation position and the pivoting of the button pivots a first cam member that pushes or pulls the first cable, thereby disengaging the first hook from the first striker.

In accordance with another aspect of the present invention there is provided a method of opening a storage bin that includes moving a button from a home position to an actuation position. Movement of the button from the home position to the actuation position moves a first cable, thereby disengaging a first hook assembly and a first striker assembly, wherein a bucket moves from a closed position to an open position. The method also includes maintaining an indicator in an indication position when a first latch assembly is engaged and a second latch assembly is disengaged.

It should be understood that any orientation of the components described herein is within the scope of the present invention.

Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-9B show an embodiment of a latch system 10. However, this is not a limitation on the present invention and the latch system 10 can be used elsewhere. As shown in FIG. 1, generally, the latch system 10 includes a paddle button assembly 12, first and second latch assemblies 14 and first and second cables 16 extending between the paddle button assembly 12 and the first and second latch assemblies 14. As shown in FIG. 2, the latch system 10 can be used with a pivot bin assembly 100, such as those used in commercial passenger aircraft. However, this is not a limitation on the present invention and the latch system 10 can be used elsewhere. Preferably, the latch system 10 is used with an aircraft storage bin 100 that includes a bucket 102 that is pivotally connected to an upper housing 104. Preferably, the upper housing 104 includes first and second side panels 106. The bucket 102 cooperates with the upper housing to define a bin interior and is movable with respect to the upper housing 104 between an open position and a closed position. In a preferred embodiment, the bucket 102 includes a bottom 108 and first and second side walls 110. In another embodiment, the bucket can also include a top. For example, see the bucket taught in U.S. Patent Publication No. 2011/0253837, published on October 20, 2011 (the “'837 publication”), the entirety of which is incorporated by reference herein.

As shown in FIG. 1, the paddle button assembly 12 includes a button 18 that is movable between a home position and an actuation position (see FIGS. 5A and 5B), the first and second latch assemblies 14 includes a first hook assembly 20 and a first striker assembly 22, and the first and second cables 16 extends between the paddle button assembly 12 and the first and second latch assemblies 14. The first and second latch assemblies 14 can be associated with the side panels and side walls of the upper housing 104 and bucket 102 or they can be associated with the front of the upper housing 104 and bucket 102. It will be appreciated that only a single latch assembly 14 can be utilized (on one side or in the middle of the bucket and upper housing).

As shown in FIG. 2, in a preferred embodiment, the paddle button assembly 12 is associated with or mounted on or in the bucket 102. However, in another embodiment, the paddle button assembly 12 can be associated with or mounted on or in the upper housing. In a preferred embodiment, the first and second hook assemblies 20 are associated with one of the bucket 102 and the upper housing 104 and the first and second striker assemblies 22 are associated with the other of the bucket 102 and the upper housing 104. The drawings show the hook assemblies 20 mounted in the side walls 110 of the bucket 102 and the striker assemblies 22 mounted in and extending downwardly from the side panels 106 of the upper housing 104. However, this arrangement can be reversed. In the embodiment shown in the drawings, the hook and striker assemblies 20 and 22 are generally aligned with the side walls and side panels, which allows the clamshell type bin to close. However, in another embodiment, the hook and striker assemblies 20 and 22 can be mounted on the inside of outside of the side walls or side panels. For example, if the latch system 10 was used with the pivot bin assembly taught in the ‘837 publication, the striker assemblies 142 could be mounted on the inner surfaces the side panels of the stationary upper housing and the hook assemblies 140 could be mounted on the outer surfaces of the side walls of the pivoting bin or vice versa.

Generally, movement of the button 138 from the home position (see FIG. 14A) to the actuation position (see FIG. 14B) moves the cables 16, thereby disengaging the hook assemblies 140 and the striker assemblies 142, thereby allowing the bucket to move from the closed position to the open position. This arrangement will be further described below.

As shown in FIG. 12, in a preferred embodiment, paddle button assembly 132 is mounted in an opening 112 defined in the bottom 108 of the bucket 102. The cables 16 extend through a channel 114 defined in either the bucket 102, between the bucket 102 and trim 116 or in the trim. FIG. 3 shows the first portion of the channel 114 extending away from the paddle button assembly 12 defined in the bucket and covered by a cover 118 (which is exploded away) and the second portion of the channel 114 defined in the top of the front and side edges of the bucket 102 and to the striker assemblies 22. In another embodiment, the first portion of the channel 114 extends away from the paddle button assembly 12 and is defined in the bucket and covered by the cover 118 and the second portion of the channel 114 is defined between the top of the front and side edges of the bucket 102 and the inner surface of the trim 116. The cables 16 can be exposed or contained in an outer casing 17, similar to cables used for braking on bicycles. The bucket 102 can also includes the cover 118 that is mounted to an inside surface thereof for covering the paddle button assembly 12, cables 16 and associated components.

The paddle button assembly 12, which is best shown in FIGS. 4-5B, will now be described. Generally, the paddle button assembly 12 includes a frame 24, the button 18, first and second cam members 26, and an indicator 28 (described below). The frame 24 defines a central opening 30 that at least partially receives the button 18 and has an outer flange 32 that is mounted against the outside surface of the bucket 102. The button 18 is pivotally connected to the frame 24 (preferably by a pivot pin 18a that extends through associated openings in the frame 24 and button 18). The frame 24 also includes a hinge portion 34 that the cam members 26 are pivotally connected to. The hinge portion 34 can be integral with the frame 24 or a separate component.

As is best shown in FIGS. 5A-5B, in a preferred embodiment, the cam members 26 are generally “L” shaped and include a button engaging end 26 a and a cable engaging end 26b. Preferably, the cable engaging end 26 b includes an opening 36 that receives a ball 16 b on the end of the cable 16. However any attachment of the cables 16 to the cable engaging ends 26 b of the cam members 26 is within the scope of the present invention. The cam members 26 are preferably received in recesses 38 in the hinge portion 34 and are pivotal with respect to the hinge portion 34 (preferably by pivot pins 26c that extends through associated openings in the hinge portion 34 and button cam members 26).

As shown in FIG. 5A, the end 18 b of the button 18 distal from the pivot point is engaged with the button engaging ends 26 b of the cam members 26 (only one cam member is shown in FIG. 5A). FIG. 5A demonstrates the home position, which, as described below is associated with the engaged position of the first trigger arm and, ultimately, the closed position of the bin. To open the bin, a user pushes on button 18, which, pivots to the actuation position (shown in FIG. 5B). In a preferred embodiment, the button 18 is biased toward the home position. This can be done by a spring 18 c. The distal end 18 b of the button 18 pushes the button engaging ends 26 a of the cam members 26, thereby pivoting the cam members 26 from a first position (shown in FIGS. 4 and 5A) to a second position (shown in FIG. 5B). The cam members 26 pulls the cables 16 (within casings 17), which ultimately disengages the hook assemblies 20 and the striker assemblies 22, which will be more fully described below. In another embodiment, the button 18 and cam member 26 are oriented to push the cable 16.

In a preferred embodiment, the cables 16 include the capability of being adjusted. This can be useful as the cables may stretch or lengthen over time. In a preferred embodiment, as shown in FIGS. 4-5B, the paddle button assembly 12 includes an adjustment lock 39 and adjustment nuts 40. The adjustment nuts 40 are similar to those used on bicycle brakes and or shifters. The adjustment lock 39 prevents the adjustment nuts 40 from turning when in the locked position and allows turning of the nuts (and, therefore, adjustment) when unlocked.

The latch assemblies 14, one of which is shown in FIGS. 6 and 7, will now be described. Generally, the hook assembly 20 includes a hook 50 that engages a striker 52 on the striker assembly 22. When the hook 50 and striker 52 are engaged, the bucket is in the closed position. When the hook 50 and striker 52 are disengaged (by actuation of the button 18), the bucket moves to the open position.

As shown in FIGS. 6 and 7, in a preferred embodiment, the striker assembly 22 includes a casing 54 that is secured to the upper housing 104 and includes a striker housing 56 extending downwardly therefrom. The striker housing 56 defines a housing interior 58. The striker 52 comprises a bushing 60 that is rotatably received on a pin 62 that spans the housing interior. In a preferred embodiment, the striker housing 56 includes three sides, thereby defining a fourth side opening 56 a that, together with the striker 52 defines a hook opening 56 b into which the hook 50 is received.

In a preferred embodiment, the hook assembly 20 includes a housing 64 that defines a housing interior that houses the other components. In a preferred embodiment, the housing 64 is received in an opening in the side wall 110 of the bucket 102. The housing 64 includes a top wall 64a that has a striker opening 64 b defined therein. Inside the housing 64, the hook assembly 20 includes a rotary member 66 and a pivotal trigger arm 68. The rotary member 66 is rotatably mounted on a pivot axle 70 and includes the hook 50 a closeout member 72 and a catch member 74. The rotary member 66 is rotatable between a first position (see FIG. 6) and a second position (see FIG. 7) and is biased toward the second position (preferably by a torsion spring that is concentric with the pivot pin). The trigger arm 68 is pivotally mounted to a pivot axle 70 and includes a ledge 76 and a ramp portion 78. The trigger arm is pivotal between an engaged position and a disengaged position and is biased toward the engaged position (preferably by a torsion spring that is concentric with the pivot pin).

As shown in FIG. 6, when the rotary member 66 is in the first position, the hook 50 is engaged with the striker 52 and the catch member 74 is engaged with the ledge 76 on the trigger arm 68. In this position, the hook 50 and striker 52 are engaged and the bucket is held in the closed position. When the cable 16 is pulled, as described above, the cable 16 pivots the trigger arm 68 to the disengaged position. In this position, the catch member 74 disengages from the ledge 76, and the rotary member 66 rotates to the second position (due to the bias). In a preferred embodiment, the catch member 74 engages a stop member 80, thereby preventing further rotation of the rotary member 66. As is shown in FIG. 7, when the rotary member 66 is in the second position, the closeout member 72 is aligned with the striker opening 64 b in the top wall 64 a of the housing 64. It will be understood that this serves two purposes. First, it prevents objects from entering the striker opening 64 b. Second, it is part of the process for rotating the rotary member 66 back to the first position when the bucket is closed. In use, when the bucket is pivoted upwardly, the striker 52 enters the striker opening 64 b and engages or contacts the closeout member 72. Because the closeout member 72 is offset from the pivot point of the rotary member 66, the engagement of the striker with the closeout member 72 causes the rotary member 66 to start to rotate toward the first position. The closeout member 72 includes a curved surface 84 that the striker 52 continues to push in to finish the rotation to the first position, thereby engaging the hook 50 with the striker 52.

As shown in FIGS. 5A-5B and FIGS. 8-9B, in a preferred embodiment, the paddle button assembly 12 includes an indicator 28 that is pivotally connected to the frame 24 (by a pivot pin) 29 and housed in an opening therein. The indicator 28 generally has a wedge shaped cross-section and is pivotal between a first position (see FIGS. 5A and 9A) where an outer surface 28a is flush with the outside surface of the flange 32 and a second position, where the side surfaces 28 b are exposed. The indicator 28 is preferably biased toward the first position. The indicator 28 indicates when one or both of the hooks 50 are not engaged with the strikers 52.

As shown in FIG. 5A, in the first position, the inner surface 28 c of the indicator 28 is biased against both cable engaging ends 26 b of the cam members 26. In use, when the button 18 is pivoted from the home position to the actuation position (as shown in FIG. 5B), the cam members 26 pivot and the cam engaging end 26 b pivots the indicator 28 to the second position, thereby indicating that the hook 50 is not engaged with the striker 52. As is described above, when the cables 16 are pulled, the trigger arms 68 are pivoted from the engaged to the disengaged position, which causes the rotary members 66 to rotate from the first to the second position. It will be appreciated that as the rotary members 66 rotate to the second position, inclined surfaces 82 on the hooks 50 engage the ramp portions 78 of the trigger arms 68, which pivot the trigger arms 68 to the disengaged position and holds them there even after the button 18 has pivoted back to the home position. This action pushes the cables 16, which, in turn holds the cam members 26 and the indicator 28 in their respective second positions, as is shown in FIGS. 8 and 9B. During latching of the hooks 50 and strikers 52, when the trigger arms 68 are both moved to the engaged position, the cables 16 are pulled, thereby pivoting the cam members 26 and the indicator 28 to their respective first positions, as is shown in FIGS. 5A and 9A. It will be understood that if the bucket is closed improperly and only one of the first and second latch assemblies is latched (i.e., one of the strikers is not engaged with its hook), the cam member 26 associated with the unlatched latch assembly will hold the indicator in the second position, thereby indicating that something is wrong. In a preferred embodiment the side surfaces 28 b of the indicator are a bright color. Therefore, when the bucket is in the closed position, but one of the latches is not properly latched a user (e.g., a flight attendant) will see that the indicator is in the position shown in FIG. 9B and can address the situation.

It will be appreciate that modifications can be made to the present invention. For example, the cable can be operably engaged with the hook and configured to pivot or rotate the hook to move the hook from a first to a second position and out of engagement with the striker. In this embodiment, the hook is biased toward the first position. To reengage the hook and striker, the hook includes an inclined surface thereon that is engaged by the striker to push the hook to the second position. Then after the striker clears the inclined surface the hook is biased back to the first position and into engagement with the striker. In this embodiment, the hook would act similar to the trigger arm in the current drawings. In the claims this embodiment may be covered by referring to the hook as a trigger arm. In another embodiment, the cable can be configured to pull or push the striker out of engagement with the hook. In another embodiment, the configuration of the button can be reversed so that the button is pulled to pivot and operate the cam members. In another embodiment, the cable is directly connected to the button so that pivoting the button pulls or pushes the cable to operate the latch. In another embodiment, the button is pushed in a linear direction to push the cable to operate the latch.

FIGS. 10-17 show another embodiment of a latch system 130. As shown in FIG. 10, generally, the latch system 130 includes a paddle button assembly 132, first and second latch assemblies 134 and first and second cables 16 extending between the paddle button assembly 132 and the first and second latch assemblies 134.

As shown in FIG. 10, the paddle button assembly 132 includes a button 138 that is movable between a home position and an actuation position (see FIGS. 14A and 14B), the first and second latch assemblies 134 includes a first hook assembly 140 and a first striker assembly 142, and the first and second cables 16 extend between the paddle button assembly 132 and the first and second latch assemblies 134.

As shown in FIG. 11, in a preferred embodiment, the paddle button assembly 132 is associated with or mounted on or in the bucket 102. However, in another embodiment, the paddle button assembly 132 can be associated with or mounted on or in the upper housing. In a preferred embodiment, the first and second hook assemblies 140 are associated with one of the bucket 102 and the upper housing 104 and the first and second striker assemblies 142 are associated with the other of the bucket 102 and the upper housing 104. The drawings show the hook assemblies mounted in the side walls of the bucket and the striker assemblies mounted in and extending downwardly from the side panels of the upper housing. However, this arrangement can be reversed. In the embodiments shown in the drawings, the hook and striker assemblies are generally aligned with the side walls and side panels, which allows the clamshell type bin to close. However, in another embodiment, the hook and striker assemblies can be mounted on the inside or outside of the side walls or side panels. For example, if the latch system 130 was used with the pivot bin assembly taught in the '837 publication, the striker assemblies could be mounted on the inner surfaces the side panels of the stationary upper housing and the hook assemblies could be mounted on the outer surfaces of the side walls of the pivoting bin or vice versa.

Generally, movement of the button 138 from the home position (see FIG. 14A) to the actuation position (see FIG. 14B) moves the cables 16, thereby disengaging the hook assemblies 140 and the striker assemblies 142, and allowing the bucket to move from the closed position to the open position. This arrangement will be further described below.

As shown in FIG. 12, in a preferred embodiment, paddle button assembly 132 is mounted in an opening 112 defined in the bottom 108 of the bucket 102. The cables 16 extend through a channel 139 defined in the bottom 108 and sides 110 of the bucket 102. FIG. 12 shows the channel 139 extending along the outside bottom of the bucket away from the paddle button assembly 132. The channel 139 is preferably covered by a cover 141. The cables 16 extend in opposite directions from the paddle button assembly 132 and to the striker assemblies 142.

The paddle button assembly 132, which is best shown in FIGS. 13-14B, will now be described. Generally, the paddle button assembly 12 includes a frame 202, the button 138 and a casing 204 for attachment to the bucket 102. FIG. 13 also shows a cover 205 for covering the paddle button assembly 132 in the inside of the bucket. The frame 202 includes first and second cam levers or cam members 206 that pivot when the button 138 is pushed and that pull the cables 16. The button 138 is pivotally connected to the frame 202 (preferably by a pivot pin that extends through associated openings 143 in the frame 202 and button 138). The frame 202 includes channels 208 defined therein that receive the cam members 206 and in which the cam members 206 pivot. The cables 16 (not shown in FIG. 13) extend through openings 210 in the end of the frame 202. Balls 16 b on the end of the cables 16 are received in an opening 212 in the cam members 206. The cam members 206 each include a cam post 214 extending outwardly therefrom. The cam posts 214 engage with a cam surface 216 on the button 138.

FIG. 14A demonstrates the home position, which, as described below is associated with the engaged position of the first trigger arm and, ultimately, the closed position of the bin. To open the bin, a user pushes on button 138, which, pivots to the actuation position (shown in FIG. 14B). In a preferred embodiment, the button 138 is biased toward the home position. This can be done by a spring. As a result of the configuration of the cam surface 216 and the cam posts 214, movement of the button 138 causes the cam posts 214 to move upwardly and inwardly on the cam surface 216 (as oriented in FIGS. 14A and 14B). This movement causes the cam members 206 to pivot from a first position (shown in FIG. 14A) to a second position (shown in FIG. 14B). The cam members 206 pull the cables 16 (within casings 17), which ultimately disengages the hook assemblies 140 and the striker assemblies 142, which will be more fully described below. In another embodiment, the button 138 and cam member 206 are oriented to push the cable 16. It will be appreciated that the frame 202 and the button 138 each include inclined surfaces 218 that maintain the cam posts 214 in the desired position prior to and during operation.

In a preferred embodiment, the frame also includes stoppers 220 that cooperate with windows 222 in the button 138. The inner upper edge of the windows 222 contact the stoppers 220 in the first position to maintain the button 138 in the first or rest position. Similar to the first embodiment described herein, the cables can include the capability of being adjusted.

The latch assemblies 134, one of which is shown in FIGS. 15-17, will now be described. Generally, the hook assembly 140 includes a hook 150 that engages a striker 152 on the striker assembly 142. When the hook 150 and striker 152 are engaged, the bucket is in the closed position. When the hook 150 and striker 152 are disengaged (by actuation of the button 138), the bucket moves to the open position.

In a preferred embodiment, the striker assembly 142 includes a casing 154 that is secured to the upper housing 104 and includes a striker housing 156 extending downwardly therefrom. The striker 152 is associated with and secured in the striker housing 156.

In a preferred embodiment, the hook assembly 140 includes a housing 164 that defines a housing interior that houses the other components. In a preferred embodiment, the housing 164 is received in an opening or indentation in the side wall 110 of the bucket 102 (see FIG. 17). The housing can include two sides that together house the hook 150 and associated components or a single side that cooperates with the side wall 110 of the bucket 102 to house the hook 150 and associated components. The housing 164 includes a striker opening 164a defined therein. Inside the housing 164, the hook assembly 140 includes a rotary member 166 and a pivotal trigger arm 168. The rotary member 166 is rotatably mounted on a pivot axle 170 and includes the hook 150, a closeout member 172 and a catch member 174. The rotary member 166 is rotatable between a first position (see FIG. 15) and a second position (see FIG. 16) and is biased toward the second position by a spring 175 (a torsion spring that is concentric with the pivot pin can also be used). The trigger arm 168 is pivotally mounted to a pivot axle 170 and includes a ledge 176 and a ramp portion 178. The trigger arm 168 is pivotal between an engaged position and a disengaged position and is biased toward the engaged position (preferably by a torsion spring that is concentric with the pivot pin or by the indicator assembly 186, described below).

As shown in FIG. 15, when the rotary member 166 is in the first position, the hook 150 is engaged with the striker 152 and the catch member 174 is engaged with the ledge 176 on the trigger arm 168. In this position, the hook 150 and striker 152 are engaged and the bucket is held in the closed position. When the cable 16 is pulled, as described above, the cable 16 pivots the trigger arm 168 downwardly to the disengaged position. In this position, the catch member 174 disengages from the ledge 176, and the rotary member 166 rotates to the second position (due to the bias by spring 175). In a preferred embodiment, in the second position, the rotary member 166 engages a stop member 180, thereby preventing further rotation of the rotary member 166. As is shown in FIG. 16, when the rotary member 166 is in the second position, the closeout member 172 is aligned with or positioned to close the striker opening 164a in the housing 164. It will be understood that this serves two purposes. First, it prevents objects from entering the housing. Second, it is part of the process for rotating the rotary member 166 back to the first position when the bucket is closed. In use, when the bucket is pivoted upwardly, the striker 152 enters the striker opening 164a and engages or contacts the closeout member 172. Because the closeout member 172 is offset from the pivot point of the rotary member 166, the engagement of the striker with the closeout member 172 causes the rotary member 166 to start to rotate toward the first position. The closeout member 172 includes a curved surface 184 that the striker 152 continues to push in to finish the rotation to the first position, thereby engaging the hook 150 with the striker 152.

As shown in FIGS. 15-16, in a preferred embodiment, the hook assembly 140 includes an indicator assembly 186 that is operatively connected to the trigger arm 168. The indicator assembly 186 includes an indicator 188 that extends through an opening 189 in the bottom of the housing 164, an arm 190 and a plunger 192 that includes a ball 193 on the end thereof that is received in a socket 194 defined in the trigger arm 168. Preferably, the arm 190 includes a spring 195 thereon that extends between the plunger 192 and a baffle 196 in the housing 164. The spring 195 biases the trigger arm 168 upwardly and the indicator 188 to a first position.

As shown in FIG. 15, when the trigger arm 168 is in the engaged position (equivalent to the hook being engaged with or latched to the striker), the indicator 188 is in the first position, thereby indicating that the hook 150 is engaged with the striker. In this position, the bottom surface of the indicator 188 is generally flush with the bottom of the housing 164. As shown in FIGS. 16 and 17, when the trigger arm 168 is in the disengaged position (equivalent to the hook being disengaged or unlatched from the striker), the trigger arm 168 pushes the plunger 192, arm 190 and indicator 188 downwardly and into a second position, thereby indicating that the hook 150 is disengaged from the striker. In this position, the indicator 188 extends downwardly through opening 189 so that it is visible to passengers or crew. Preferably, the indicator is colored red (or other color) to provide greater visibility. The indicator 188 can also include a light.

As shown in FIGS. 15-17, in a preferred embodiment, the indicator assembly 186 also includes a manual override switch or member 198 that is positioned in and movable within a switch opening 200 in the housing 164. FIGS. 15-16 show the back side of the switch and FIG. 17 shows the front side. The manual override switch 198 is used if the bucket will not open using the button 138 (i.e., when moving the button does not cause the hook assembly to disengage from the striker assembly). In use, the manual override switch is moved from a first position (FIG. 15) to a second position (FIGS. 16 and 17) (e.g., it is moved generally downwardly), which pulls and pivots the trigger arm 68 to the disengaged position. In this position, the catch member 174 disengages from the ledge 176, and the rotary member 166 rotates to the second position (due to the bias), thereby disengaging the hook 150 from the striker 152. In another embodiment, the indicator can be omitted. In this embodiment, the indicator assembly is also referred to as an override assembly.
